Experten haben den jährlichen Bericht vorgestellt, der politischen Entscheidungsträgern die neuesten und wichtigsten klimawissenschaftlichen Forschungsergebnisse an die Hand, um die Verhandlungen auf der COP28 und die Umsetzung der Politik bis 2024 und darüber hinaus zu unterstützen.
Das internationale Cabo-Verde-Atmosphären-Observatorium (CVAO) wird weiter ausgebaut: Der Präsident der Republik Cabo Verde José Maria Neves und Bundespräsident Frank-Walter Steinmeier legten am Donnerstag den Grundstein für ein neues Laborgebäude auf São Vicente, einer der Kapverdischen Inseln vor Afrika. Das Max-Planck-Institut für Biogeochemie war am Aufbau der Station beteiligt und führt seitdem am CVAO Langzeitmessungen u.a. der Treibhausgase Methan, Kohlendioxid und Lachgas durch.
Zur COP27 in Ägypten reisten auch neun Max-Planck-Wissenschaftlerinnen und -Wissenschaftler, unter Ihnen Dr. Carlos Sierra, Gruppenleiter am Max-Planck-Institut für Biogeochemie in Jena. Im Interview vermittelt Tom Sparks Eindrücke und Einschätzungen zur Rolle der Wissenschaft.
A new study shows that future ecosystem functioning will increasingly depend on water availability. Using recent simulations from climate models, an international team of scientists found several “hot spot regions” where increasing water limitation strongly affects ecosystems. These include Central Europe, the Amazon, and western Russia.
You can't see them with the naked eye, but our forest ground is littered with microorganisms. They decompose falling leaves, thereby improving soil quality and counteracting climate change. But how do these single-celled organisms coordinate their tasks? An international research team has been looking into this little-understood process. The results of the study were recently published in Scientific Reports.
Scientists have succeeded in detecting changes in carbon dioxide emissions from fossil fuels much faster than before. Using a new method, they combined atmospheric measurements of carbon dioxide (CO2) and oxygen (O2) from the north coast of the United Kingdom. The study, with the participation of the Max Planck Institute for Biogeochemistry, was published Apr. 22 in Science Advances.
International researchers found a pattern of extreme climate conditions leading to forest dieback. To do this, the team had collected worldwide records of climate-related tree and forest dieback events over the past nearly five decades. The results, recently published in Nature Communications, reveal an ominous scenario for forests in the context of ongoing global warming.
International forest experts analyzed major tree and forest dieback events that occurred globally in the last decades in response to climate extremes. To their surprise many forests were strongly affected that were not considered threatened based on current scientific understanding. The study, led by the MPI-BGC and published in Annual Reviews in Plant Biology, underscores also that further tree and forest dieback is likely to occur.
An international research team succeeded in identifying global factors that explain the diversity of form and function in plants. Led by the University of Zurich, the Max Planck Institute for Biogeochemistry in Jena and the University of Leipzig, the researchers collected and analyzed plant data from around the world.
Precisely how does a forest system and the individual plants within it react to extreme drought? Understanding the processes involved is crucial to making forests more resilient in the increasingly dry climate that will result from climate change, and also important for refining climate models. A research team led by Prof. Dr. Christiane Werner from the University of Freiburg has conducted the most extensive experiment to date into this subject using stable isotopes to trace flows of water and carbon through a forest.
The increasing amount of greenhouse gases in the atmosphere is causing our climate to warm at an alarming rate. Information is vital for societies who must decide on pathways to climate neutrality. The European ICOS research structure, including Max-Planck Institute for Biogeochemistry, provides this information, as described in a recent article.
Ecosystems provide multiple services for humans. However, these services depend on basic ecosystem functions which are shaped by natural conditions like climate and species composition, and human interventions. A large international research team, led by the Max Planck Institute for Biogeochemistry, Jena, identified three key indicators that together summarize the integrative function of terrestrial ecosystems.
